The present invention relates to a structure to reduce noises by aerodynamic force. More specifically, the present invention relates to an aerodynamic noise reducing structure in an area with a high Reynolds number which can reduce aerodynamic noises of an object operated in an area with a high Reynolds number more than or equal to a hundred thousand unit. The aerodynamic noise reducing structure in an area with a high Reynolds number has an uneven part or a plurality of protrusions in an outer surface of an object having a circular, oval, or rectangular cross section.

    본 발명은 공력에 의한 소음을 저감하기 위한 구조에 관한 것으로, 더욱 상세하게는 십만 단위 이상의 고 레이놀즈수 영역에서 운용되는 물체의 공력 소음을 저감시킬 수 있는, 고 레이놀즈수 영역에서의 공력소음 저감 구조에 관한 것이다.
